Securing Data in The Cloud

I just found an interesting article about securing your data in the cloud. Now that cloud computing has gained quite a number of followers, it will be good to understand the additional necessary steps to ensure your confidential data are secured in a cloud computing environment.

The original article can be found here.

Storing data in the cloud is arguably the most important aspect of public cloud resources, but it is rarely treated as such. Two practical steps to take when securing cloud data are:

  • Protect your data in a real world environment.
  • Meet compliance requirements.

What are the issues?
There are two primary issues that we have to deal with when talking about data security in a public cloud:

  • Protection of the data: Dealing with the confidentiality, integrity, and availability (CIA) criteria. Answering the important questions, such as, “What is the risk to the data? Are the controls in place adequate to mitigate the risk?”
  • Location of the data: Dealing with the physical location of the “bits” and answering questions like, “Do I know where the data resides? Does this violate any of my compliance requirements?”

Location is often doubly important because we do not think about it; it may easily slip by unnoticed and have significant impact if a data loss ever occurs.

An example is the conflict between the U.S. Patriot Act and Canadian laws on the privacy of certain personal information. The U.S. government says if there is a compelling reason, they are able to see data in their jurisdiction. Canadian laws say that the data of certain Canadian citizens is protected and cannot be disclosed. If you handle Canadian data (i.e., data that is protected), then you had better be sure it is not physically located on systems in the U.S. Note that this is something providers will need to ensure via contracts.

Google Chrome on Ubuntu (well, sort of)

Most of us already know that one of the fastest browser out there is Google Chrome. Sadly enough, Google Chrome is only available on Windows platform, while the Mac and Linux users are left to run Safari or Firefox. The good thing is that Google has listened to those requests and are currently developing the native version of Chrome to Mac and Linux.

But for those who can’t wait, there is a way to get Chromium (the open-source platform on which Google Chrome is based). Here are the steps (originally taken from here):

First you need to edit the /etc/apt/sources.list file:

     sudo gedit /etc/apt/sources.list

Add add the following lines if you are using Ubuntu 9.10 (Karmic Koala):

     deb karmic main
     deb-src karmic main

Save and exit the file.

Now add the GPG key using the following command:

     sudo apt-key adv –recv-keys –keyserver 0xfbef0d696de1c72ba5a835fe5a9bf3bb4e5e17b5

Update the source list using the following command:

     sudo apt-get update

Then you can install chromium using the following command:

     sudo apt-get install chromium-browser

After a successful installation, you can open chromium from Applications—>Internet—>Chromium Web Browser:

Here’s a sample picture of what Chromium looks like on Ubuntu:
[singlepic id=262 w=320 h=240 float=center]

Alternatively, there’s a script created by Jeff Rader to automate the installation of Chromium. His script can be downloaded here. Do not forget to change the permission to executable before running the script.


10 Most Useful Google Plugins for WordPress

Original post is located here.

WordPress is a great and most popular blogging platform for it possibility to extend functions with plugins. WordPress Plugins make blogging easier for all of us who have chosen WordPress as our content management system. This time we want to present you 10 Most Useful Google Plugins for WordPress.

Google is best known as a search engine and Internet giant, but this time we will check what Google can offer for WordPress users. This post lists the most useful WordPress plugins related to Google starting from XML Sitemaps and ending with FeedBurner subscribers counter.

We also are using some of listed plugins like Google XML Sitemaps, Google Analyticator or FeedBurnerCount.

1. Google XML Sitemaps

This plugin will create a Google sitemaps compliant XML-Sitemap of your WordPress blog. It supports all of the WordPress generated pages as well as custom ones. Everytime you edit or create a post, your sitemap is updated and all major search engines that support the sitemap protocol, like, Google, MSN Search and YAHOO, are notified about the update.

2. Google Analyticator

Google Analyticator easily adds Google Analytics tracking support to a WordPress-powered blog. Google Analyticator also comes with an easily customizable widget that can be used to display specific information that is gathered by Google Analytics using the Google Analytics API.

3. Google Analytics for WordPress

This plugin adds the possibility to tag and segment all outgoing links, so you can see whether a click came from a comment or an article. It also adds the possibility to track just the domain, instead of the complete link, so you get a better view of how much traffic you’re sending where.

4. Google Website Optimizer for WordPress

This simple plugin lets you optimize your landing pages (as posts or pages) using the Google Website Optimizer without needing to edit the HTML code of the theme.

5. Google Doc Embedder

Google Doc Embedder will allow you to embed a PDF, PowerPoint (PPT), or TIFF file directly into your page or post, not requiring the user to have Adobe Reader, PowerPoint, or other software installed to view the contents.

6. Easy AdSense

Easy AdSense provides a very easy way to generate revenue from your blog using Google AdSense. With its full set of features, Easy AdSense is perhaps the first plugin to give you a complete solution for everything AdSense-related.

7. XML Google Maps

This plugin allows you to easily insert Google Map or Google Earth Plugin Maps into your blog.

8. Google AJAX Translation

The Google AJAX Translation WordPress plugin provides a quick, simple, and light way to add translation to your blog. A “Translate” button can be added to the bottom or top of posts, pages, and/or comments.

9. Google Custom Search Plugin

The default search engine that ships with WordPress is not the best search engine and bloggers every where should make the switch to WordPress Google Custom Search plugin. This plugin is a drop in replacement and works with minimum hassle.

10. FeedBurnerCount

A well-optimized and reliable plugin that connects to the FeedBurner Awareness API to retrieve your readers count, that you can print out in plain text.

As for me, I have been using Google XML Sitemap and Google Analytics for WordPress. Might want to try the other plugins when I have the chance to do so. 🙂

10 Unknown but Useful Linux Terminal Commands

The original post was here.

Before, I have posted here a few basic Linux terminal commands that I think are essential for newbies to know. I’ve also shared some deadly ones that should be avoided at all costs. This time, I’m going to show you several terminal commands that are perhaps unfamiliar to many new-to-Linux users but could be really handy when used properly.

Here’s a list of 10 rather unknown yet useful Linux terminal commands:

1. Kill a running application by its name:
      killall [app_name]

2. Display disk space usage:
      df –h

3. Locate the installation directories of a program:
      whereis [app]

4. Mount an .iso file:
      mount /path/to/file.iso /mnt/cdrom –o loop

5. Record or capture a video of your desktop:
      ffmpeg -f x11grab -s wxga -r 25 -i :0.0 -sameq /tmp/out.mpg

6. Find out the Universally Unique Identifier (UUID) of your partitions:
      ls /dev/disk/by-uuid/ -alh

7. Show the top ten running processes (sorted by memory usage):
      ps aux | sort -nrk 4 | head

8. Make an audible alarm when an IP address goes online:
      ping -i 60 -a IP_address

9. Run the last command as root:
      sudo !!

10. Make a whole directory tree with one command:
      mkdir -p tmp/a/b/c

Note: There are some problems on doing number 9 above, so you may want to try it out and let me know.

Update (14 Jul 2010) : I have deactivated Sociable, and use three new plugins: Tweetmeme, WP Google-Buzz, and FaceBook Share. Those are pretty much the ones people are using to share links anyway these days. 🙂
